1. (1) issuing a "do not resuscitate order for emergency medical services";

2. (2) good faith reliance on a "do not resuscitate order for emergency medical services" resulting in:

   1. (a) the withholding of resuscitative treatment; or
   2. (b) the withholding of resuscitative treatment already in progress once a duly executed "do not resuscitate order for emergency medical services" is identified;
3. (3) initiating resuscitative treatment on a "do not resuscitate patient" if EMS personnel were unaware of the existence of the order or if EMS personnel reasonably and in good faith believed the "do not resuscitate order" had been cancelled or revoked; or
4. (4) initiating resuscitative treatment on a "do not resuscitate patient" where in the best medical judgment of EMS personnel, the care was necessary to relieve pain or suffering or to provide comfort care to the patient.
